Griess Reagent
Griess Reagent is a chemical used for the colorimetric detection of nitrite ions in aqueous samples, commonly employed in environmental and biological testing. It consists of a mixture of sulfanilic acid and N-(1-naphthyl)ethylenediamine dihydrochloride, forming a diazonium salt that produces a pink azo dye upon reaction with nitrite. CAS: 1465-25-4, Molecular Formula: C12H14N2·2HCl, Molecular Weight: 259.17 g/mol, Storage: Ambient, Signal Word: Warning. Molekula supplies Griess Reagent from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
